Question about Panasonic CT-27HL14 27" TV

1 Answer

Picture goes out frequently

This is actually a Panasonic CT-27614A model - but it's likely close enough. The picture will go out, but I took the screws out of the clamshell & separated it slightly - then it works fine - until the next time. The solution has been to either open or close (or otherwise adjust) the clamshell until the picture remains on. At one time, I took the clamshell completely off - but could not see anything that was loose. I also can't identify what is getting adjusted by openning or closing the clamshell. It's annoying because if the clamshell is too far open, the remote doesn't work unless you're 2 feet from the set. A bestbuy tech looked at it a year ago - but he didn't know what was wrong - which is how I wound up with the set (my father in law gave it to me & bought a new one)

Re: picture goes out frequently

You could have a very small crack in the main circuit board. To find this you'd have to pull the board and flex it slightly and/or use an insulated and non conducting object such as a plastic rod and tap the board all over until you find a sensitive place. You have to do this with the set turned on. If you're not experienced at this type of trouble shooting, you need to get a qualified tech to do it for you. These sets usually require the use of an isolation transformer to protect you for being shocked. Also you need to know how to work around high voltage circuits. There's several thousand volts on your picture tube. Also you need to make sure you don't cause a short when the board is out of it's holder and in operation. Be careful ! Stargazer

Does a CT-27614A need a digital converter for antenna?

I hope this soultion is helpful.

How can I be sure that I am buying a digital TV (DTV)?
By law, beginning March 1, 2007, all television reception devices (including TVs, VCRs, DVRs, etc.) imported into the U.S. or shipped in interstate commerce must contain a digital tuner. Retailers may continue to sell analog-only devices from existing inventory, but must prominently display on or near the analog-only device a Consumer Alert label with this advisory:

What is the difference between “Integrated” DTVs and DTV or HDTV “Monitors”?
An Integrated DTV set is a television with a built-in digital tuner (also referred to as “a DTV”). A digital tuner is also sometimes called a DTV decoder or DTV receiver. If you have an Integrated DTV, you will not need any additional equipment, with the exception of a broadcast antenna (either a rooftop antenna or “rabbit ears” connected to the set), to receive over-the-air digital broadcast programming. Integrated DTVs can also receive and display analog broadcast programming, so you can continue watching analog broadcasts.
In contrast, a DTV Monitor is not capable of receiving digital broadcast programming without additional equipment; it is simply a display device without the processing capability for DTV reception. A digital or HD set-top box must be connected between the antenna and the monitor to receive and display over-the-air digital or HD programming.
If you have a digital or HD “Monitor” and would like to purchase a digital or HD set-top box to view over-the-air programming, confirm with your retailer that the set-top box is compatible with your Monitor.

Tv color

The solder joints on the degaussing thermistor have cracked or the thermistor itself has opened, and the CRT is heavily gaussed. You can degauss (demagnetize) the picture tube and the colors should return to normal, but the thermister should be resoldered or replaced.
